AIX RAC CRS安装错误案例
环境：
操作系统： AIX 5.3.8
集群软件： CRS 10.2.0.1
数据库： Oracle 10.2.0.1
1、案例
在一台安装过crs的aix 节点上重新安装crs ，出现以下错误：
[root@/aix211]# /u01/crs_1/root.sh
WARNING: directory '/u01' is not owned by root
Checking to see if Oracle CRS stack is already configured
Checking to see if any 9i GSD is up

-------跳过vote disk 的format ，直接启动，系统hang 住
解决方法：
重新卸载crs ，并清理ocr 和 vote disk
[root@/aix211]# cd /u01/crs_1
[root@/u01/crs_1aix211]# rm -rf *
[root@/u01/crs_1aix211]# ls /etc |grep ora
oraInst.loc
oracle
[root@/u01/crs_1aix211]# rm /etc/oraInst.loc
[root@/u01/crs_1aix211]# rm -rf /etc/oracle
[root@/u01/crs_1aix211]# cd
重新配置ocr 和 vote disk 磁盘属性
[root@/aix211]# chown -R oracle:oinstall /u01/crs_1
----- 清理ocr 和 vote disk
[root@/aix211]# dd if=/dev/zero of=/dev/rrac_ocr bs=8192 count=12800

[root@/aix211]# dd if=/dev/zero of=/dev/rrac_vote bs=8192 count=2560

[root@/aix211]# ls -l /dev |grep ocr

------再次安装crs ，并运行root.sh 脚本，正常
